The Event_Dispatcher acts as a notification dispatch table.
|
|
It is used to notify other objects of interesting things. This
|
|
information is encapsulated in Event_Notification objects. Client
|
|
objects register themselves with the Event_Dispatcher as observers of
|
|
specific notifications posted by other objects. When an event occurs,
|
|
an object posts an appropriate notification to the Event_Dispatcher.
|
|
The Event_Dispatcher dispatches a message to each registered
|
|
observer, passing the notification as the sole argument.
